Prominent Harvard political scientist accused of xenophobia for the content of his books, most especially The Clash of Civilizations and the Remaking of World Order (1996). In it, Huntington predicts that the history of the 21st century will be dominated by struggle between human cultures and not individual countries:

It is my hypothesis that the fundamental source of conflict in this new world will not be primarily ideological or primarily economic. The great divisions among humankind and the dominating source of conflict will be cultural. Nation states will remain the most powerful actors in world affairs, but the principal conflicts of global politics will occur between nations and groups of different civilizations. The clash of civilizations will dominate global politics. The fault lines between civilizations will be the battle lines of the future.
